摘　　要：我国地形地貌多样,气候分区明显,且人多地少,耕地面积紧缺,土地资源利用效率不高。随着土地资源的逐步开发利用,退化土地这一科学问题也逐渐得到行业内学者的重视,在退化土地防治工作中,土壤质量改良剂作为改善土壤质量的重要因子,逐步被学界重视,本文从我国土地退化概况以及几类常用的退化土地土壤质量改良剂进行分析和阐述,以期剖析不同改良剂的施用范围和作用机理。China’s topography and landscape are diverse, climate partitioning is obvious, and there are many people and little land, arable land is scarce, and the efficiency of land resource utilization is not high. With the gradual development and utilization of land resources, the scientific problem of degraded land has gradually gained the attention of scholars in the industry, and in the prevention and control of degraded land, soil quality improvers as an important factor to improve soil quality have gradually been emphasized by the academic community. In this paper, the general situation of land degradation and several kinds of soil quality improvers used in degraded land in China were analyzed and expounded to analyze the application range and action mechanism of different improvers.
